Connecting to Your DB Cluster Using IAM Authentication

With IAM database authentication, you use an authentication token when you connect to your DB cluster. An authentication token is a string of characters that you use instead of a password. After you generate an authentication token, it's valid for 15 minutes before it expires. If you try to connect using an expired token, the connection request is denied.

Every authentication token must be accompanied by a valid signature, using AWS signature version 4. (For more information, see Signature Version 4 Signing Process in the AWS General Reference.) The AWS CLI and the AWS SDK for Java can automatically sign each token you create.

You can use an authentication token when you connect to Amazon Aurora from another AWS service, such as AWS Lambda. By using a token, you can avoid placing a password in your code. Alternatively, you can use the AWS SDK for Java to manually create and manually sign an authentication token.

After you have a signed IAM authentication token, you can connect to an Aurora DB cluster. Following, you can find out how to do this using either a command line tool or the AWS SDK for Java.
